The present invention relates to solorouncliug or sole rounding and channeling machines, and is intenclezjl primarily as L11iI11- prorenent on the machine disclosed in Petent No. 599,602, granted to Z. T. French and W. (3. Meyer February 22, 1898,

In the machine of Patent No. 599,602 the position of the shoe with relation to the trimming-lrnife is controlled by two guides, one 01" Which controls the position of the shoe while the shank portion of the sole is being trirninetl and the other of which controls the position of the shoe while the fore part of the solo is being trinune The fore pert guide is mounted to move into and out of contact with the shoe and also to move while in en guge'uent with the shoe to vary the position of the shoe with relation to the trimminglrnile. The shank-guide is also movably mounted and is moved with the fore port guide while the fore part of the sole is being tri nineil, so as to remain in cents-ct With the upper surf-Lice of the welt and prevent the for nation n ri thereon, would be the vit the shank-guide were stationery. in 1 echiue ul in all sols ouniii 0 use with rich 1 nm lnnu. 3 :Lshzmlc-guiilc null :1. ion shin guiijle is in its extrcit tionwhilo the shank portion oftl tri'nnioii, so that the shzmli portion of e sole is trimmed as close to the upper on any portion of the fore part.

on the outsole-stitcher extremely difficult, if not impossible.

The object of in r invention is to obviate the difficulty above referred to in the operetion of sole-rounding machines and to produce a solerounding machine com rising a shenloguide and a foreart guide y which the fore port of the so e of ejshoe can be trimmed as close to the upper es may be desired without triinniing the shank portion of the sole so close as to interfere with the operation of the outsole-stitcher.

W'ith this object in view my invention contemplates providing n sole-rounding machine comprising a shank-guide and e fore-part guide with nieans for relatively moving the shank-guide and trimming-knife to allow the lore port of the sole to he trimnied closer to the upper than the shank portion.

Broadly considered, my invention contemplates the provision in a soleq'ounding machine comprising a shank-guide, a forepert guide, and a triiniring-lrnife of any means l'or re "ively moving" the shenlcguide and the trnnnringmite to allow the fore part of the sole to be trimmed closer to the upper than the shank portion. On account of the simplicity of such at construction and its certainty of operation, however, I prefer to secure the relative move'nent of the shank guide and trimming-knife by retracting the shanle zuicle.

In addition to the features of invention above referred to my invention also consists in the devices, combinations, and arrangements of parts hereinafter described and cleiniecl the advantages of which Wlll be obus to lose sl lletl in the ert.

preferred form of my invention is illusil in the accompany n15; chewing, which rates in sectional elevation a rough inning and channeling machine embody he some, the machine being that (lisclosed in Patent No. 599,602, above referred to, and much of the machine being illusiteil as is necessary to show the connection 0 *ention therewith.

Referring to the drawing 1 indicates the work-support, 2 the clxannclingl nife, 3 the tri'inn'iinggkni'le i the shank-guide, and 5 the fore-hart guide, these parts and the various other ports illustrated on the clrou ing and not hereinafter specifically referred ICO to being constructed, arranged, and operated in the same manner as the corresponding parts of the machine of Patent No. 599,602.- As in the machine of the patent, the shank-guide is secured to an arm 6, pivoted'at 7 on the frame of the machine and pressed upwardly by means of a spring 8. The fore-part guide 5 is mounted upon an arm 9, which is rigidly secured to a pivotshaft 10. The arm 9 is held raised in the position illustrated in the drawing by means of a spring (not shown) and is moved to brin the fore-part guide 5 into engagement with the shoe at the proper time during the sole-rounding operation by means of a ioot-treadle connected to the arm by means of the chain 11, the construction of the arm 9 and the means for actuating the arm to move the fore-part ide into and out of engagement with the s cc being the same as in the machine of -the patent. When the arm 9 is depressed to bring the fore-part guide into engagement with the shoe, an adjustable block on the arm engages a projection 12 on theshank-guide, so that while the fore-part 5 guide is in engagement with the shoe the shank-guide is moved with the fore-part I guide when the fore-part guide is moved to vary the position of the shoe with relation to thetrimming-knife, this construction and mode of'opcration being also the same as in the machine of the patent.

In carrying out my present invention I have provided means for holding the arm 6 depressed against the tension of spring 8 while the tore-part guide 5 is in its raised position and for releasin the arm and allowing it to rise during the downward movement of the fore-part guide into engagement with the shoe. The shank-guide 41's thus lield'in projected position during the trimming of the shank portion of the sole and is retracted when the fore-part guide is moved toward the shoe, so that the whole or any portion of the fore-part of the sole can be trimmed closer to the upper than the shank portion. The means which I have illustrated/in the drawing for accomplishing this result consists .of 'a cam-block 13, mounted to move w th the arm 9 and to engage the upper surface of the arm 6 or a plate 14, secured thereto, the construetion being such that when the arm 9 is in its raised position. the cam-block 13 en- I gages the plate 14 and holds the arm 6 deressed, and when the arm 9 is lowered to ring the fore- Jart guide 5 into engagement with the shoe t 1e cam-block 13 is moved out of engagement with the plate 14 to allow the the arm 9. The screw-threaded rod is held in position by means of clampingnuts 16, which serve to clamp the split hub of the arm 9 to the pivot-shaft 10, and also as a means of adjustment for the cam-block 13. By adjusting the cam-block 13 the distance to. which the arm 6 and shank-guide 4 are depressed when the fore-part guide is in its raised position and the distance to which the shank-guide is retracted during the move.-

ment of the fore-part guide toward the shoe can be varied as desired. V

It Wlll be understood that except for the retracting movement of the shank-guide when; the fore-part guide is moved toward the shoe the operation of the various'parts illustrated in the drawing is the same as that of the corresponding parts of the machine disclosed in Patent No. 599,602. 1 Thus after the fore-part guide is brought into engagement with the shoe it may remain stationary during the operation of rounding the fore part of the sole, or it may be moved tovary the position of the shoe with relation to the trimming-knife. The construction and mode of operation of the machine is fully illus trated and described in Patent No. 599,602, and further description and illustration thereof in this application is considered unnecessary.

Having thus indicated the nature and scope of my invention and having specifically described a. construction embodying a preferred form tl1ereof,-I claim as new and desire to secure by Letters Patent of the United I States 1. A' sole-rounding machine, having, in combination, a trinnningknife, a shankguide, a fore-part guide movable into and out of engagement with the shoe, and means for relatively moving the shank-guide and trimming-knife to allow the fore part of the sole to be trimmed closer to the upper thanthe shank portion, substantially as described.

2. A sole-rounding machine, having, in combination, a trimming-knife, a shankguide, a fore-part guide, and means for moving the fore part guide into operative position and for retracting the shank-guide, substantially as described.

3. A sole-rounding machine, having, in combination, a trimming-knife, a fore-part guide movable into and out of engagement with the shoe and movable to vary the position. of the shoe with relation to the trimming-knife, a shanlcguide movable with the fore-part guide'when in engagement with the shoe, and means for retracting the shankguide when the fore-part guide is moved into engagement with the shoe, substantially as described. i
